This research investigated the impact of network topologies on the performance of
OpenFlow protocol. OpenFlow Protocol is a southbound protocol over Secure
Socket Layer (SSL) in Software Defined Networking (SDN). SDN architecture
separates the intelligence (decision making) part (control plane) of network devices
from forwarding capability (data plane). OpenFlow protocol is the communication
protocol for exchanging control messages between control plane and data plane. The
research investigation was based on the performance of OpenFlow protocol version
1 on four topologies; unconnected switches, linear, tree, and typical DCN. POX
software was used as controller in control plane.
The motivation behind the study is based on the fact that topology in SDN is
discovered by exchanging lldp based control messages. Despite the impact of lldp
based control messages on the performance of SDN, to the knowledge of this study
the impact of network topologies on the performance of OpenFlow protocol is yet to
be explored. The research adopted mininet emulation tool to simulate four
topologies. The performance of OpenFlow protocol was measured in terms of
throughput and delay. This data was observed through wireshark. Descriptive
statistical analysis of data was done through Wireshark and Microsoft excel 2010.
It was found that the throughput of OpenFlow protocol in terms of packet per second
(pps) is highest in typical DCN and lowest in unconnected switches. OpenFlow
protocol in typical DCN topology transfers higher number of information with lower
delay than any other topologies simulated in this environment.
